Answer / ravinder tanwar
It depends on quqlity of cable and generally it is
specified by the cable manufacturer that for a perticular
distance what will be the loses and we add that quantity in
our logic for accurate value

bcoz use the specialy manufactured t/c cable and for each
type of t/c we use different t/c cable of that t/c material

Answer / jayakrishnan unnikrishnan
First upon CCR not receiving any mv,it is receiving only ma.
mv is going to the transmiter and the transmiter giving
output to panel and console.
& voltage drop , Thermo couple extension cable is not a
normal signal cable it is depends on the thermocouple type.
consider K type thermocouple so the extension cable should
be Nickel Aluminium, b'coz Nickel Chromium is the K type.
it will avoid voltage drop.

Answer / ponnamalla venkata satish
thats why we use single stand not multi core cable for
thermocouple measurement

Answer / rajesh
Each type of themocouple different types of metals winding are used Example k-type of thermo couple used cromium aluminium metals are used, like j,s,t ect. This metals used as per thermo couple mvolts droping is reducedu

Answer / aebrahim
the resistance of thermocouple is les than resistance of
normal cable so voltage drop across wire not too big
